Figure 62. Turning speed results
The results are displayed in Hz and RPM.
To measure the rotation speed with the stroboscope set the estimated rotation
speed and direct the light flux transmitted by the stroboscope to the rotating
rotor. If the defined rotation speed of the rotor and the flicker frequency of the
stroboscope coincide, a “stationary machine” effect occurs. Therefore the flicker
frequency of the stroboscope should be changed till the effect occurs. To change
the flicker frequency of the stroboscope use the navigation keys. The Up and Down
buttons change the rotation speed or frequency in Hz at the following intervals:
1) in Hz - 0,1
2) in RPM - 10.
The Left and Right buttons change the rotation speed and frequency in Hz at the
following intervals:
1) in Hz - 0,01
2) in RPM - 1.
